Description

Technical Field

[0001] This utility model relates to the field of screening technology for building stone processing, specifically a screening device with an anti-clogging structure for building stone processing. Background Technology

[0002] Sand and gravel are widely used in building stone due to their good hardness and stable chemical properties. However, because different sand and gravel have different structures, particle sizes, and uses, they need to be screened to classify them by size.

[0003] According to the patent application CN215313836U, a screening device for building stone processing is described as follows: "This utility model relates to the field of building stone processing technology and discloses a screening device for building stone processing, including a processing box. A feed funnel is fixedly connected to one side of the top of the processing box. A screen frame is installed inside the processing box. A reciprocating mechanism is provided on one side of the bottom of the screen frame. The reciprocating mechanism includes an eccentric wheel, a strip plate, a movable rod, and a return spring. The eccentric wheel is located below one side of the screen frame, the strip plate is located at the top of the eccentric wheel, the movable rod is fixedly connected to the top of the strip plate, and the return spring is sleeved on the outside of the movable rod. A first discharge port and a second discharge port are opened on one side of the processing box. This screening device for building stone processing, through the design of the reciprocating mechanism and the screen frame, utilizes the reciprocating operation to realize the reciprocating swing of the two sides of the screen frame around the fixed seat as the center, and then realizes the screening of building stone under the swing of the screen frame, effectively avoiding the problem of screen hole clogging during the screening operation."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] Although this utility model can screen building stone through its reciprocating mechanism and screen frame, in practical applications, the device can only screen the building stone once. Due to the oscillation of the reciprocating mechanism, some of the stone is introduced into the discharge port before it can be screened, resulting in poor screening effect. In addition, a lot of dust is easily generated during the screening process, which, if not treated, can pose a threat to the health of operators. Therefore, we urgently need to improve the screening equipment for building stone processing with an anti-clogging structure to solve the above problems. Utility Model Content

[0028] Example 1:

[0029] Please see Figure 1-5 This utility model provides a technical solution: a screening device with an anti-clogging structure for processing building stone, including an outer frame 1, a support leg 2 fixedly installed at the bottom of the outer frame 1, a feed hopper 3 fixedly installed at the top of the outer frame 1, an anti-clogging screening mechanism 4 provided inside and outside the outer frame 1, and a dust collection mechanism 5 provided on the back of the outer frame 1.

[0030] The anti-blocking screening mechanism 4 includes an anti-blocking screening component 41 and a secondary screening component 42, with the anti-blocking screening component 41 located outside the secondary screening component 42.

[0031] Furthermore, the anti-clogging screening component 41 includes a first mounting frame 411, which is fixedly installed inside the outer frame 1. A screen plate 412 is rotatably installed inside the first mounting frame 411. A baffle 413 is fixedly installed on the top of the screen plate 412. A connecting frame 414 is fixedly installed on the outside of the screen plate 412. A motor base 415 is fixedly installed on the back of the outer frame 1. A first motor 416 is fixedly installed inside the motor base 415. A crankshaft 417 is fixedly installed on the output shaft of the first motor 416. A connecting plate 418 is fixedly installed on the outside of the crankshaft 417. A guide plate 419 is provided inside the outer frame 1 to facilitate the screening of the added building stone raw materials and prevent the raw materials from accumulating on the surface of the screen plate 412 and causing clogging.

[0032] Furthermore, the connecting plate 418 and the connecting frame 414 are rotatably installed, and the guide plate 419 is set at an angle to facilitate the guiding and screening of the added building stone raw materials.

[0033] Furthermore, the secondary screening component 42 includes a return hopper 421, which is fixedly installed on the right side of the outer frame 1. An adjusting plate 422 is slidably installed inside the return hopper 421. A second mounting bracket 423 is fixedly installed outside the outer frame 1. A return pipe 424 is fixedly installed at the bottom of the return hopper 421. A second motor 425 is fixedly installed inside the return pipe 424. A spiral auger shaft 426 is fixedly installed on the output shaft of the second motor 425. This component can perform secondary screening of raw materials larger than the screen holes of the screen plate 412, thereby improving the screening effect.

[0034] Furthermore, the spiral auger shaft 426 is rotated and installed inside the return pipe 424. The top of the return pipe 424 faces the inside of the feed hopper 3. The outer frame 1 and the return hopper 421 are provided with a material leakage groove to facilitate secondary screening. After screening, the stone raw materials that fall back into the return hopper 421 can be discharged.

[0035] Example 2:

[0036] Please see Figure 6 Furthermore, in conjunction with Embodiment 1, the dust collection mechanism 5 includes a connecting frame 51, which is fixedly installed on the back of the outer frame 1. A filter frame 52 is slidably installed inside the connecting frame 51. A fixing frame 53 is fixedly installed inside the connecting frame 51. A fan 54 is provided outside the fixing frame 53. A connecting pipe 55 is fixedly installed on the top of the connecting frame 51. A dust suction head 56 is fixedly installed on the side of the connecting pipe 55 away from the connecting frame 51. This mechanism can collect and process the dust generated during the screening process, preventing it from directly drifting into the operating environment and posing a threat to the health of the operators.

[0037] Furthermore, the outer frame 1 has an installation groove at the corresponding position of the dust collection head 56, and the connecting frame 51 has a connecting hole on the outside, which facilitates the effective collection of dust during the screening process.

[0038] In actual operation, when this device is used, the building stone granules to be processed can first be added from the top of the feed hopper 3 into the outer frame 1. Then, the first motor 416 is turned on, causing the crankshaft 417 to rotate, which in turn causes the connecting plate 418 to rotate synchronously, pulling the connecting frame 414. Under the action of the first mounting frame 411, the screen plate 412 can be shaken to achieve shaking screening of the building stone granules. Building stone granules smaller than the screening holes will fall to the bottom of the outer frame 1 and leak out. The remaining granules are guided into the return hopper 421 by the guide plate 419 as the screen plate 412 shakes. To improve the screening effect, the second motor 425 can be turned on to rotate the auger shaft 426, thereby controlling the return hopper 421. The building stone raw materials inside 21 are transported. Under the guidance of the return pipe 424, the raw materials can fall back into the feed hopper 3 for secondary screening. After repeated screening several times, the raw materials fall back into the return hopper 421. The adjusting plate 422 can be pulled to allow the building stone raw materials in the return hopper 421 to leak out for classified storage. During operation, in order to avoid generating too much dust during screening, the blower 54 can be turned on to generate air. With the help of the connecting pipe 55 and the dust suction head 56, the debris generated during screening can be collected. At the same time, with the help of the filter frame 52, the dust can be collected in a concentrated manner. After the screening is completed, the dust inside can be uniformly treated.
